Pump steam trap UNA 25-PK

Ball-float steam traps with pump function

The use of compact UNA 25-PK units guarantees drainage without banking-up, and a leakproof seal in all operating conditions.

In addition to the tried-and-tested rolling ball regulator, a mechanism is incorporated that independently conveys higher pressure steam into the body when the upstream pressure is low. With this booster steam, the condensate is actively fed into the condensate system. When the pressure in the heat exchanger is sufficiently high, the rolling ball regulator works like a conventional ball-float steam trap.
